2020 Lexus GS: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the mostly carryover 2020 Lexus GS is the late-arriving GS 350 F SPORT Black Line Special Edition. The GS 300 trims also leave the lineup, while the GS F receives a few blacked-out exterior details.
About the 2020 Lexus GS
4th generation (2013-2020), final model year before the GS was discontinued in the US.
Lexus positions the GS as a midsize luxury sport sedan that blends traditional Lexus comfort and craftsmanship with sharper road manners than a typical comfort-first sedan. The core appeal is a smooth naturally aspirated engine, rear-drive-based balance, a quiet and carefully finished cabin, and available AWD on GS 350 models. In 2020, it stands as Lexus’ more driver-focused luxury sedan for shoppers who want polish and responsiveness in the same car.
The GS 350 remains the comfortable core model, pairing a 311-hp V6 with a 12.3-inch navigation display and a standard safety suite. The GS 350 F SPORT adds sharper suspension tuning and sportier cabin details, while the GS F stands apart with a 467-hp V8, large Brembo brakes, and track-focused hardware.

Styling
The new GS 350 F SPORT Black Line Special Edition adds gloss-black wheels and exterior trim, plus a black-and-red cabin with carbon-fiber and Alcantara surfaces. The GS F gains standard matte-black wheels, black mirror caps, and blacked-out B-pillars.
